> Can anyone suggest a viable alternative for the TI graphing calculator? It's not cheaper, but while taking some nightschool math classes a couple of years ago I bought an HP Prime[0], which was new on the market then. It's a truly excellent calculator which puts the TIs to shame. It's a calculator with a modern multitouch interface so you can use pinch-to-zoom on graphs, etc. It uses the xCas engine[1] as a backend and has a spiffy calculator frontend, so you can write formulas as they would appear in a textbook. EDIT: It also has an ARM processor, IIRC around 300MHz. It really shows when graphing complex equations, where the TIs take forever. I hear the newest TI nSpire ones have a slightly more modern CPU, but I really hate the interface there (it's no longer really a calculator for me, but a shitty tablet). If you want an actual physical calculator, I strongly recommend this one.
